| 20120116227 | ULTRASONIC BLOOD VESSEL INSPECTING APPARATUS - An ultrasonic blood vessel inspecting apparatus provided with a longitudinal cross sectional blood vessel image generating portion configured to generate a longitudinal cross sectional image of a blood vessel located below a skin of a live body, on the basis of reflected wave signals of an ultrasonic wave by using an ultrasonic probe placed on the skin of said live body, includes: an index value calculating portion configured to calculate an index value indicative of a degree of clarity of an image which represents an intima-media complex of said blood vessel and which exists within said longitudinal cross sectional image of the blood vessel. | 05-10-2012 |
| 20120095332 | BLOOD VESSEL FUNCTION INSPECTING APPARATUS - A blood vessel function inspecting apparatus including blood flow velocity distribution measuring portion for measuring a blood flow velocity distribution within a blood vessel in a non-invasion manner with ultrasonic waves before releasing of the blood vessel from a blood flow obstruction or after a blood vessel diameter measuring time period; viscosity-shear rate relationship calculating portion; and blood shear stress calculating portion for measuring a blood flow velocity within the blood vessel, concurrently with the measurement of a change ratio of the diameter of the blood vessel within the predetermined blood vessel diameter measuring time period after releasing of the blood vessel from the blood flow obstruction, and calculating a blood shear stress on the basis of a measured blood flow velocity, and according to a viscosity-shear rate relationship. | 04-19-2012 |
| 20120089020 | BLOOD VESSEL FUNCTION INSPECTING APPARATUS - A blood vessel function inspecting apparatus including a first blood state index value calculating portion that obtains estimated hematocrit values at a plurality of points predetermined within a blood vessel, on the basis of values of a blood viscosity and values of a shear rate at said plurality of points, which are respectively extracted from a viscosity distribution and a shear rate distribution, and according to reference relationships between a hematocrit value and the blood viscosity, which reference relationships respectively correspond predetermined different values of the shear rate; and a second blood state index value calculating portion that calculates, as said blood state index value, a value relating to an amount of difference of the estimated hematocrit values at said plurality of points with respect to each other, which amount is minimized by transforming said reference relationships at the same ratio for all of the values of the shear rate. | 04-12-2012 |
| 20110319771 | VITAL LUMINAL PART EVALUATING APPARATUS - A pressure vessel is provided with an annular inflation bag and an annular inflation bag for sealing the pressure vessel at intermediate positions of brachium and antebrachium of the live body in longitudinal direction of the arms of the live body, and is configured to permit a change of an internal pressure therein over a pressure range a lower limit of which is a negative value, while a portion of the brachium and antebrachium between first and second positions in the longitudinal direction is accommodated in the pressure vessel, so that the pressure vessel can be comparatively small-sized even where arterial vessel (luminal part) of a comparatively large diameter is accommodated in the pressure vessel, whereby the physical and mental burden on the subject person can be reduced. | 12-29-2011 |
| 20100210946 | BLOOD VESSEL ULTRASONIC IMAGE MEASURING METHOD - A blood vessel ultrasonic image measuring method capable of facilitating the positioning of an ultrasonic probe and acquiring sufficient positioning accuracy is provided. Because of inclusion of an around-X-axis positioning step of causing a multiaxis driving device 26 to position an ultrasonic probe such that distances from respective ultrasonic array probes to the center of a blood vessel are equalized, and an X-axis direction positioning step and an around-Z-axis positioning step of causing the multiaxis driving device to position the ultrasonic probe such that the image of the blood vessel is positioned at the center portion in the width direction of the first short axis image display area G1 and the second short axis image display area G2, the positioning may be performed by using the positions in the longitudinal direction of the ultrasonic array probes relative to the blood vessel or the distances of the ultrasonic array probes to the blood vessel and, therefore, the ultrasonic probe may simply and easily be positioned on the blood vessel of a living body with higher accuracy. | 08-19-2010 |
| 20090036776 | Apparatus for measuring inner diameter of tubular body of living being - An apparatus for measuring an inner diameter of a tubular body present under a skin of a living being, by emitting an ultrasonic wave from an ultrasonic probe placed on the skin, the apparatus including a reflection-signal detecting portion which detects a reflection signal that is reflected from the tubular body when the ultrasonic wave is emitted from the ultrasonic probe; and an inner-diameter calculating portion which calculates the inner diameter of the tubular body, based on an interval between two groups of reflection waves which are contained by the detected reflection signal and which are reflected from two diametrically opposed portions of a wall of the tubular body, respectively. | 02-05-2009 |
